Bununu howardite是一种多混合物风化角砾岩，其中含有冲击熔体，主要限于1 cm厚的侵入体，其中含有残余玻璃。与马尔文一样，熔融岩石中含有陨石镍钴含量的熔体。从该组合物形成玻璃的冷却速率为每分钟零点几度。侵入性熔融岩是布努努特有的特征，可能表明布努努是在撞击熔融时固结的。
The Bununu howardite is a polymict regolith breccia which contains impact melt that is largely restricted to a 1-cm thick intrusion containing residual glass. As in Malvern, the melt rock contains melt with meteoritic Ni-Co contents. The cooling rate, interpreted for forming glass from this composition, is a few tenths of a degree per minute. The intrusive melts rock, which is a feature unique to Bununu, may indicate that Bununu was consolidated at the time of impact melting.
